解决apt-get依赖(unmet dependencies)问题

好几个月没开steam，想上商店看看，可是启动steam就报错，

You are missing the following 32-bit libraries, and Steam may not run: libGL.so.1

按照这篇帖子，一步一步解决问题，最后一步又卡了壳，

* 解决steam报错找不到libGL.so.1问题方案，


1- If you haven't updated your computer in a while, copy (ctrl+c) and paste (ctrl+SHIFT+v) this (and then hit enter to run it). If you don't know what this is, just do it. :

Code:

sudo apt-get update && sudo apt-get -y upgrade

2- If you've installed Steam already, skip to step 3. If you haven't installed Steam, open Terminal with ctrl+alt+t. Then copy (ctrl+c) and paste (ctrl+SHIFT+v) this (and then hit enter to run it):

Code:

sudo apt-get install -y steam

3- Now for the fix. Copy (ctrl+c) and paste (ctrl+SHIFT+v) this to edit Steam's configuration file (and then hit enter to run it):

Code:

sudo nano /etc/ld.so.conf.d/steam.conf

4- It'll probably be blank. If it's blank, paste these two lines. If it's not blank, just paste these two lines to the very bottom. Copy (ctrl+c) and paste (ctrl+SHIFT+v) this (and then enter to run it):

Code:

/usr/lib32
/usr/lib/i386-linux-gnu/mesa

5- Save it by hitting ctrl-x, then y, then enter.

6- Now copy (ctrl+c) and paste (ctrl+SHIFT+v) this (and then hit enter to run it).:

Code:

sudo ldconfig

7- Finally, copy (ctrl+c) and paste (ctrl+SHIFT+v) this (and then hit enter to run it). It reinstalls a Mesa/OpenGL library:

Code:

sudo apt-get install --reinstall libgl1-mesa-glx:i386

8- Open Steam, download Team Fortress 2, and go kill some folks.

可是到了如上第七步骤的时候，有错误啦，

The following packages have unmet dependencies:
.................

二逼如我，按照依赖的package名字，挨行敲入

sudo apt-get install PACKAGENAME

可总是有如下类似错误，即安装不成功

0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded

然后Google一番，终于找到了解决方案，

* 无敌神龙命令出来啦！

sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade

自动修复这个依赖问题，自动安装缺失的包。太棒了。

至于更多的apt-get参考这篇帖子，解释的非常翔实。
